nu x llll 1 UNITED STATES' PATENT SAMUEL C. BOLE, OF GONEMAUGHPENNSYLVANIA, ASSIGNOR OF ONE- HALF HIS RIGHT TO J OIIN'l?.` KLINGENSMITH, OF SAME PLAGE.

IMPRovEMENTiN GAR=COUPLINGS.

Specification forming part of Letters Patent No. 133,S24, dated December l0, 16753.

To all whom it may concern ABe it known that I, SAMUEL C. BoLE, of

I i Conemaugh, county of Cambria, Pennsylvania, have invented certain Improvements in Car-Couplings, of which the following is a specification My invention has for its object to improve the construction of carcouplings in such manner 'as to render it possible to couple cars without` endangering the lives or limbs of those employed in making-up trains. To this end the invention consists in the combinationof two hookjaws and a drop or set pin in such a manner that the jaws can be set open preparatory to coupling; and that they will close automatically and interlock corresponding jaws the moment the cars come usedn connection with the common link and A is the draw -bar, which forms guides in which the coupling hangs.v The draw-bar is supported by the stirrup B, and attached to the car by the king-bolt C in the usual manner. D is the coupling, which consists of the upper jaw F and the movable lower jaw I. E is astrong wrought-iron strap, (one end of which forms the jaw F,) bent at right angles at a and b, the end cl extending forward nearly tothe plane of the jaw F. G is a cast-iron strengthening-block, which is secured within the frame formed by the stra-p E by means of bolts and rivets. I is the lower or movable jaw, made of a flat bar'of wrought-iron, bent and forged into the shape shown in the drawing. The upper part of this bar forms a lever, I', bywhich the jaw is raised or lowered.` The pin Kgpasses through the lever I', which swings on the f pin, the

r ends of the pin being supported by the strap E, which is slotted to allow the @ver to pass through it, a corresponding slot being made in the upper part of the strap E, in which slot the lever I' and drop-pin L fitf This drop -pin is held in contact with the lever I by the band M, which is secured to the lever; and the drop-pin has a movement parallel to the lever, being drawn up when the coupling is set, as shown in Fig. 2. The drop-pin is drawn down into the slot S by its own weight andthe pressure of the spiral spring N, which rests in grooves cut in the i pin and lever; and when in this position it locks the lever securely in the slot S and prevents its falling forward, and the dropping of the jaw I. The hooks o o are made of steel, riveted to the wrought-iron jaws at a welding heat. The couplingis hung between the guides AA on the pin H, which passes through the gumspring packing T, which is fitted between the strap E and the strengthening-block Gr. This spring relieves the jar occasioned by the two couplings coming together. The coupling has a slight move ment around the pinH, but is prevented from dropping by the stirrup B.

The coupling is set by raising the droppin L and throwing the lever I forward, which depresses the lower jaw, as shown in Fig. 2. When the couplings come together the points of the jaws of one coupling strike the lever I of the opposite coupling and throw it back, closing the jaws, and allowing the drop-pin L to fall and seat itself in the slot S, the hooks on the jaws interlocking, as shown by dotted lines in Fig. 2.

Fig. 3 shows the position of the coupling when used on cars of different heights.

When coupling with cars using the link and pin the link isinserted between the .jaws F and L, and the pins dropped through the holes P P, as before described.

In uncoupling, the drop-pins.of .both coup-` lings are raised and set, as shown in Fig. 2.

With couplings of the above described construction it is not necessary for anyone to stand between the cars to couple them.

What I claim as new is-.

1. The jaws F and I, lever I', drop pin L, strap E, and strengthening-block G, when 4arranged and operating substantially as and for the purpose specified.

2. The combination of thel jaws F and I and gumspring T with the draw -bar A, as

specified.
